It looks like from the video of this, the side that the train was moving under was the first side to go, the vibrations from the train moving could have resonated the bridge enough to stress the weakest points of the bridge.
mythbusters did a story about the resonate frequency of structures. They used a vibration exciter to bring down a building by using it at the resonate frequency of the structure. My theory is that the train just happened to resonate the bridge at its frequency.
Either way my thoughts and prayers to the familys of the people who are still missing.
